Solar Energy Solutions

Solar Systems Design

Etajoule specializes in the the design of industrial and commercial scale solar projects. It is uniquely experienced in the design and recovery of solar thermal projects with recent experiences in St. Croix, Dominica, Hawaii, Puerto Rico, Aruba, and Florida ranging from multifamily low-income housing to 5-star hotels and military facilities.  

Research and Development

Aerogel Insulated Collector

We are also developing a solar collector for process temperatures between 100ºC - 200ºC that promises efficiencies above 45%. This effort merited a winning project in the Round 4 of the American Made Solar Prize competition. This technology would allow us to use energy directly from the sun to produce steam at low pressures. 


Modular Solar Drying Kiln

Our team has developed a revolutionary technological solution that uses an aerogel as an insulator in the collection area of the solar collectors. This system will be designed to improve the performance of solar collectors in agro-industrial applications.

The thermal energy extracted from the sun will be used in a mobile dryer that can be used in different agricultural applications. For example, wood drying, dehydration of fruits and condiments, pasteurization or any other application requiring heat. 


The system will be designed to be as autonomous as possible, using mostly clean energy and intended for use in rural areas.  The mobile dryer will be designed with a solar collector system located at the top of the dryer and will be connected to an energy storage system that will allow the dryer to operate during non-sunny hours. In addition, high-efficiency insulating materials will be used to reduce heat loss and improve the energy efficiency of the system.

We are starting with agriculture...

Heat is >40% of the United States's primary energy consumption. Flat plate solar collectors have proven to be a reliable technology. Enhancing the performance of flat plate collectors to produce industrial grade process heat would be greatly advantageous. This is the solution Etajoule is developing thanks to the aerogel material produced by Aeroshield. Given the temperature requirements and heating fuel costs of the agricultural sector. Etajoule wants to center its next research and development efforts demonstrating the value of solar industrial process heat in the agricultural sector.
